Now in greeting card aisles, a new product for pranksters: cards that double as whoopie cushions.

American Greetings Corp. on Friday unveiled the line of cards that can make embarrassing sounds, aptly named "It's a gas!"

The Cleveland-based company says each whoopie cushion-turned-card in the collection can be signed and sent in an accompanying envelope.

The nation's largest publicly traded greeting card company has about 2,000 employees in northeast Ohio.
